Step-by-step explanation:

Perimeter of semicircle =

Half of circumference of circle + diameter of circle =

$\pi \: r + 2r \\ \\ = \frac{22}{7} \times 5.6 + 2 \times 5.6 \\ \\ = 22 \times 0.8 + 11.2 \\ \\ = 17.6 + 11.2 \\ \\ = 28.8 \: mm$

Burger King sells burgers for $3.50 per burger. On Fridays, you can buy 2 burgers and get 1 free. They sold 500 burgers in 1 wee

Answer:

More information is needed, maximum weekly profit is $1750.

Step-by-step explanation:

The maximum profit would assume Burger King does not sell any burgers on Friday, therefore all 500 burgers were sold at $3.50. 500*$3.50 = $1750 in maximum earnings for the week. More information is needed about the split between the burgers sold over the week.

Maybe the question was trying to say 500 burgers were sold on Friday. In that case, assuming every customer got three burgers, 500/3 = 166.6 customers, rounding down because you cannot have half a customer, 166 customers on Friday. Each customer paid for two burgers 166*2*$3.50 = $1162 in earnings on Friday.
